Sustainable Production of Concrete using Coir Fibres

Abstract

This paper reports the investigation conducted in India using coir fibres as an additive substance used in the preparation of sustainable concrete mixtures. It is meant to be used as energy-saving building components. The coir fibres were added in different percentages 2%, 4%, and 6%, and to compare the results of these the reference concrete was also prepared without coir fibres. The study focuses on investigating the different parameters such as workability, density, water absorption, compressive strength, flexural strength, and split tensile strength. The concrete blends were made while maintaining a constant water cement ratio of 0.52. The results of this study revealed that the addition of coir fibres in concrete mixes enhances the mechanical properties of concrete. An optimal percentage was proposed as 4 percent for the addition of coir fibres in concrete. It is possible to produce sustainable concrete with the use of coir fibres.
